This is my go-to dictionary – Nihongo - Japanese Dictionary Review

I use google translate as well, but this app seems to find the correct meaning better than even google translate. I like that I can search either English or romaji terms in the same search box. My only regret is that I did not buy this app when it was less expensive. I have the lite version and find the pricing to be too expensive for pro.
